Los grandes grupos económicos : Ganadores y perdedores en la post-convertibilidad : Un estudio basado en la trayectoria del sector servicios y en el nuevo rol del Estado [2002-2010]

A lo largo de la post-convertibilidad el esquema de los ganadores y perdedores entre los grandes grupos económicos 'pertenecientes al sector servicios, financiero, agro-industrial, industrial, petrolero-minero' se fue redefiniendo. Este trabajo de cuenta de tales cambios a partir de considerar los estudios sociales más importantes sobre el tema, que incluyen tanto el problema de la crisis de la convertibilidad como la nueva situación de los grandes grupos económicos y el Estado durante la post-convertibilidad. De esta manera es de suponer como necesario comenzar con una conceptualización de la crisis de la convertibilidad y sus consecuencias, para entender la situación y los problemas que debieron solucionar los grandes grupos económicos y el Estado a comienzos de la post-convertibilidad para impulsar un proceso de crecimiento económico sostenido. Así las dicotomías presentes entre los trabajos que priorizan, por un lado, la lucha entre fracciones, y, por otro, el peso de la crisis, nos servirá para dicho fin. En segundo lugar se analizaran los diferentes trabajos que explican, de diversas maneras, la nueva situación en que se encontraron -y se encuentran- las fracciones de la burguesía, y su relación con las funciones del Estado a lo largo de la post-convertibilidad. De aquí saldrán los principales insumos para pensar el rol del Estado -bajo un nuevo tipo de arbitraje- y las acciones de los grandes grupos económicos, ambos condicionados por la crisis de la convertibilidad y el mercado mundial. Con las conceptualizaciones aceptadas, se analizará la acción de los grandes grupos económicos y las funciones del Estado para un caso específico: los grandes grupos económicos de las empresas privatizadas y su relación con el nuevo tipo de arbitraje estatal en la post-convertibilidad, según dos periodos diferentes. Y, se redefinirá el esquema de ganadores y perdedores para tal caso, teniendo como elemento distintivo la relación de las empresas privatizadas y los subsidios

Trade Credits under Imperfect Enforcement: A Theory with a Test on Chinese Experience

It is widely recognized that trade credit is an important financial mechanism, particularly in developing economies and transition economies where institutions are weak. This paper documents theoretical analysis and empirical accounts on what facilitates an effective supply of trade credit based on original surveys conducted in P.R. of China. Our theory predicts that trade volume and trade credit are increasing function of cash held by the buyer and enforcement technology of the seller. Furthermore, if the state sector’s enforcement technology is high, it has positive external effect to expand the volumes of trade credit and trades in the whole economy. From the data, we found that government made active commitment in enforcement of trade credit contract and the government owned firms are main supplier and receivers of trade credit, which suggest that enforcement by government and state sector were effective against presumptions in the previous literatures.

Black economic empowerment in the South African agricultural sector : a case study of the wine industry

This paper explores the extent and forms of black economic empowerment (BEE) in the South African agricultural sector through a case study of the wine industry in the Western Cape. Compared to the mining and fisheries sectors, the progress of BEE in the agricultural sector is still in the early stage. However, various forms of black entry into the wine industry, not limited to BEE deals by large corporations, began to emerge, especially since the enactment of the Broad-based Black Economic Empowerment Act (BBBEE Act), Act 53 of 2003. This paper identifies two types of BEE wineries as unique forms of black entry into the wine industry and investigates in detail their features, backgrounds and challenges by referring to several prominent examples of each type of BEE winery.

Response of local producers to agro-food port rejection : the case of Chinese vegetable exports

This paper analyzes the factors associated with the rejection of products at ports of importer countries and remedial actions taken by producers in China by taking as an example one of the most competitive agro-food products of China: frozen vegetables. This paper provides an overview of the vegetable production and distribution system in China and the way in which China has been participating in exports of these products. Later sections will examine in detail the frozen vegetable sector in China, identify the causes of port rejections, and the actions taken by the Chinese government and by producers, processors and exporters to improve the quality of frozen vegetable exports.

How does firm heterogeneity information impact the estimation of embodied carbon emissions in Chinese exports?

Using an augmented Chinese input–output table in which information about firm ownership and type of traded goods are explicitly reported, we show that ignoring firm heterogeneity causes embodied CO2 emissions in Chinese exports to be overestimated by 20% at the national level, with huge differences at the sector level, for 2007. This is because different types of firm that are allocated to the same sector of the conventional Chinese input–output table vary greatly in terms of market share, production technology and carbon intensity. This overestimation of export-related carbon emissions would be even higher if it were not for the fact that 80% of CO2 emissions embodied in exports of foreign-owned firms are, in fact, emitted by Chinese-owned firms upstream of the supply chain. The main reason is that the largest CO2 emitter, the electricity sector located upstream in Chinese domestic supply chains, is strongly dominated by Chinese-owned firms with very high carbon intensity.

Governance Structure Choices in Supply Chain Management Evidence from Spanish and Chinese Pork Chain Cases

The author participated in the 6 th EU Framework Project ―Q-pork Chains (FP6-036245-2)‖ from 2007 to 2009. With understanding of work reports from China and other countries, it is found that compared with other countries, China has great problems in pork quality and safety. By comparing the pork chain management between China and Spain, It is found that the difference in governance structure is one of the main differences in pork chain management between Spain and China. In China, spot-market relationship still dominates governance structure of pork chain, especially between the numerous house-hold pig holders and the great number of small slaughters. While in Spain, chain agents commonly apply cooperatives or integrations to cooperate. It also has been proven by recent studies, that in quality management at the chain level that supply chain integration has a direct effect on quality management practices (Han, 2010). Therefore, the author started to investigate the governance structure choices in supply chain management. And it has been set as the first research objective, which is to explain the governance structure choices process and the influencing factors in supply chain management, analyzing the pork chains cases in Spain and in China. During the further investigation, the author noticed the international trade of pork between Spain and China is not smooth since the signature of bi-lateral agreement on pork trade in 2007. Thus, another objective of the research is to find and solve the problems exist in the international pork chain between Spain and China. For the first objective, to explain the governance structure choices in supply chain management, the thesis conducts research in three main sections. 10 First of all, the thesis gives a literature overview in chapter two on Supply Chain Management (SCM), agri-food chain management and pork chain management. It concludes that SCM is a systems approach to view the supply chains as a whole, and to manage the total flow of goods inventory from the supplier to the ultimate customer. It includes the bi-directional flow of products (materials and services) and information, and the associated managerial and operational activities. And it also is a customer focus to create unique and individual source of customer value with an appropriate use of resources, leading to customer satisfaction and building competitive chain advantages. Agri-food chain management and pork chain management are applications of SCM in agri-food sector and pork sector respectively. Then, the research gives a comparative study in chapter three in the pork chain and pork chain management between Spain and China. Many differences are found, while the main difference is governance structure in pork chain management. Furthermore, the author gives an empirical study on governance structure choice in chapter five. It is concluded that governance structure of supply chain consists of a collection of rules/institutions/constraints structuring the transactions between the various stakeholders. Based on the overview on literatures closely related with governance structure, such as transaction cost economics, transaction value analysis and resource-based view theories, seven hypotheses are proposed, which are: Hypothesis 1: Transaction cost has positive relationship with governance structure choice Hypothesis 2: Uncertainty has positive relationship with transaction cost; higher uncertainty exerts high transaction cost Hypothesis 3: The relationship between asset specificity and transaction cost is positive Hypothesis 4: Collaboration advantages and governance structure choice have positive relationship11 Hypothesis 5: Willingness to collaborate has positive relationship with collaboration advantages Hypothesis 6: Capability to collaborate has positive relationship with collaboration advantages Hypothesis 7: Uncertainty has negative effect on collaboration advantages It is noted that as transaction cost value is negative, the transaction cost mentioned in the hypotheses is its absolute value. To test the seven hypotheses, Structural Equation Model (SEM) is applied and data collected from 350 pork slaughtering and processing companies in Jiangsu, Shandong and Henan Provinces in China is used. Based on the empirical SEM model and its results, the seven hypotheses are proved. The author generates several conclusions accordingly. It is found that the governance structure choice of the chain not only depends on transaction cost, it also depends on collaboration advantages. Exchange partners establish more stable and more intense relationship to reduce transaction cost and to maximize collaboration advantages. ―Collaboration advantages‖ in this thesis is defined as the joint value achieved through transaction (mutual activities) of agents in supply chains. This value forms as improvements, mainly in mutual logistics systems, cash response, information exchange, technological improvements and innovative improvements and quality management improvements, etc. Governance structure choice is jointly decided by transaction cost and collaboration advantages. Chain agents take different governance structures to coordinate in order to decrease their transaction cost and to increase their collaboration advantages. In China´s pork chain case, spot market relationship dominates the governance structure among the numerous backyard pig farmer and small family slaughterhouse 12 as they are connected by acquaintance relationship and the transaction cost in turn is low. Their relationship is reliable as they know each other in the neighborhood; as a result, spot market relationship is suitable for their exchange. However, the transaction between large-scale slaughtering and processing industries and small-scale pig producers is becoming difficult. The information hold back behavior and hold-up behavior of small-scale pig producers increase transaction cost between them and large-scale slaughtering and processing industries. Thus, through the more intense and stable relationship between processing industries and pig producers, processing industries reduce the transaction cost and improve the collaboration advantages with their chain partners, in which quality and safety collaboration advantages be increased, meaning that processing industries are able to provide consumers products with better quality and higher safety. It is also drawn that transaction cost is influenced mainly by uncertainty and asset specificity, which is in line with new institutional economics theories developed by Williamson O. E. In China´s pork chain case, behavioral uncertainty is created by the hold-up behaviors of great numbers of small pig producers, while big slaughtering and processing industries having strong asset specificity. On the other hand, ―collaboration advantages‖ is influenced by chain agents´ willingness to collaborate and chain agents´ capabilities to cooperate. With the fast growth of big scale slaughtering and processing industries, they are more willing to know and make effort to cooperate with their chain members, and they are more capable to create joint value together with other chain agents. Therefore, they are now the main chain agents who drive more intense and stable governance structure in China‘s pork chain. For the other objective, to find and solve the problems in the international pork chain between Spain and China, the research gives an analysis in chapter four on the 13 international pork chain. This study gives explanations why the international trade of pork between Spain and China is not sufficient from the chain perspective. It is found that the first obstacle is the high quality and safety requirement set by Chinese government. It makes the Spanish companies difficult to get authorities to export. Other aspects, such as Spanish pork is not competitive in price compared with other countries such as Denmark, United States, Canada, etc., Chinese consumers do not have sufficient information on Spanish pork products, are also important reasons that Spain does not export great quantity of pork products to China. It is concluded that China´s government has too much concern on the quality and safety requirements to Spanish pork products, which makes trade difficult to complete. The two countries need to establish a more stable and intense trade relationship. They also should make the information exchange sufficient and efficient and try to break trade barriers. Spanish companies should consider proper price strategies to win the Chinese pork market

Efficient management of available technologies. Aplication to mining operations for industry supplies

Nowadays, processing Industry Sector is going through a series of changes, including right management and reduction of environmental affections. Any productive process which looks for sustainable management is incomplete if Cycle of Life of mineral resources sustainability is not taken into account. Raw materials for manufacturing are provided by mineral resources extraction processes, such as copper, aluminum, iron, gold, silver, silicon, titanium? Those elements are necessary for Mankind development and are obtained from the Earth through mineral extractive processes. Mineral extraction processes are operations which must take care about the environmental consequences. Extraction of huge volumes of rock for their transformation into raw materials for industry must be optimized to reduce ecological cost of the final product as l was possible. Reducing the ecological balance on a global scale has no sense to design an efficient manufacturing in secondary industry (transformation), if in first steps of the supply chain (extraction) impact exceeds the savings of resources in successive phases. Mining operations size suggests that it is an environmental aggressive activity, but precisely because of its great impact must be the first element to be considered. That idea implies that a new concept born: Reduce economical and environmental cost This work aims to make a reflection on the parameters that can be modified to reduce the energy cost of the process without an increasing in operational costs and always ensuring the same production capacity. That means minimize economic and environmental cost at same time. An efficient design of mining operation which has taken into account that idea does not implies an increasing of the operating cost. To get this objective is necessary to think in global operation view to make that all departments involved have common guidelines which make you think in the optimization of global energy costs. Sometimes a single operational cost must be increased to reduce global cost. This work makes a review through different design parameters of surface mining setting some key performance indicators (KPIs) which are estimated from an efficient point of view. Those KPIs can be included by HQE Policies as global indicators. The new concept developed is that a new criteria has to be applied in company policies: improve management, improving OPERATIONAL efficiency. That means, that is better to use current resources properly (machinery, equipment,?) than to replace them with new things but not used correctly. As a conclusion, through an efficient management of current technologies in each extractive operation an important reduction of the energy can be achieved looking at downstream in the process. That implies a lower energetic cost in the whole cycle of life in manufactured product.

Uso de Data Mining e do ECR para incremento da competitividade de pequenas e médias empresas: um estudo multicaso sobre varejo e indústria alimentícia

O setor supermercadista sofreu grandes alterações nos últimos anos, principalmente com o avanço das tecnologias, a competição, a concentração e algumas insuficiências em seus processos. Estes e outros fatores favoreceram ao surgimento do movimento de ECR (Resposta de Consumidor Eficiente) que procura criar um relacionamento mais forte entre indústria e varejo através de novas visões para suas estratégias operacionais. A evolução das tecnologias de informação permitiram ao setor varejista gerar uma maior volume de dados a partir, principalmente, de seus check-outs. Entretanto, estes dados nem sempre são armazenados de forma correta ou utilizados de forma a se aproveitar a plenitude das informações neles contidas. O processo de transformar os dados em informação e conhecimento vem evoluindo constantemente. Uma das atuais metodologias de trabalhar dados é o Data Mining ou Mineração de Dados, que pode ser descrito como sendo uma variedade de ferramentas e estratégias que processam dados aumentando a utilidade destes em bancos de dados. Este trabalho analisa através de um estudo multicaso exploratório na região de Ribeirão Preto, no interior de São Paulo, a avaliação da capacidade do uso da tecnologia Data Mining para o fortalecimento do movimento ECR, principalmente em pequenos e médios varejistas e indústrias alimentícias, no sentido de oferecer a estes um diferencial de negociação para formação de alianças estratégias.

‘The oil friendship’: the state of and prospects for Russian-Chinese energy cooperation. OSW Commentary NUMBER 197|17.02.2016

The oil sector has been the major element of Russian-Chinese energy cooperation. The years 2013–2015 saw a significant increase in the volume of crude oil exported by Russia. In 2015, China became the main importer of Russian oil; Russia became the second largest supplier of oil to the Chinese market, after Saudi Arabia. From Beijing’s perspective, supplies of Russian oil are of strategic importance because the main supply routes are overland routes. Russia, for its part, is interested in boosting its export because of its deteriorating position on the European market, which hitherto has been considered a strategic market.

The debt, the stock market and the state-owned enterprises. The sources of chaos on the Chinese financial markets. OSW Commentary NUMBER 201/16.03.2016

The government’s extensive programme for stimulating the economy has enabled China to maintain high economic growth after the global financial crisis in 2008. However, this success has come at the price of a number of negative economic phenomena and the consequences they have had are the major challenge for the government today. The vast programme of investments in infrastructure, construction and fixed assets, which has been the main source of economic growth over the past few years, has caused a rapid increase in China’s debt from 158% of GDP in 2007 to 282% in 2014. Along with the local governments in charge of implementing the programme, the Chinese sector of state-owned enterprises (SOEs) has been heavily burdened by the stimulation policy. The sector’s profitability has fallen, its indebtedness has increased and management problems have been revealed.
